Unformatted text preview: process with labeled streams is shown below: QuickTimeª and a decompressor are needed to see this picture. We have also assumed that the ambient temperature is 25 degrees Celsius, and therefore the difference is 40 degrees C, giving us a flat plate collector efficiency of around 70 percent. The other two types of collectors do not offer a substantial increase in efficiency at this temperature difference. Therefore we determined that the collector must be 0.53 square meters in size in order to fulfill the energy output requirement of 25kW. In our condenser we have decided to use water as a cooling fluid, with its flow rate being 5 kg/s. cc : Tobias Hanrath...
